“…Combining triboelectric effect and thermoelectric effect, Chen et al have developed a self-powered pressure-temperature dual-functional sensor as e-skin in Figure 5c. [133] The device is constructed with three layers: the pressure sensing layer relies on the triboelectric effect with patterned PDMS and PET as the triboelectric materials, ITO and PEDOT:PSS/ MWCNTs as the electrode materials. At the same time, the Cu-PEDOT:PSS/MWCNTs also serves as the temperature sensing layer together with the below PET.…”

as the components of the IoT network, and they will generate massive data with multidimensions, higher velocity, and improved heterogeneity. [2] Benefiting from this, our world is developing toward a smarter and more well-knit green earth, covering essential blocks like smart homes, smart agriculture, smart cities, smart industries as well as outer space and airlines. [3] In the green earth, the IoT systems are promising to be spread in every smart area, consisting of various sensing modules, signal processing modules, power management modules, power supply modules, etc. Sensing modules are applied to collect abundant information from the target objects or environment, such as temperature, humidity, light intensity, gas concentration, pressure, etc. And the signal processing modules help with the data transmission, processing, and analysis to connect and exchange information with other devices or systems to provide an optimal command to the target object or environment. In addition, the power management modules and power supply modules are to provide the most efficient solutions to reduce the overall power consumption in the operations of the IoT systems. [4][5][6] Thus, looking at the whole earth, it is to be closely connected with the IoT systems, enabling information transfer and communication over the strong network.Narrowing down to a single object like the human body, a single animal, or a robot, wearable electronics have attracted increasing research interest owing to their promising applications in real-time and precious monitoring and tracking of user's preferences and habits on the green earth. [7][8][9][10] Conventional wearable electronics involve smart watches, smart glasses, smart helmets, etc., while most of them are fabricated from nonflexible or rigid materials, resulting in limited wearable comfort, device lifetime, latency response, and loss of sensing information. [11][12][13] To address these issues, the current research focuses on the investigation of sensing materials with flexibility or even stretchability, breathability, washability, lightweight, adhesiveness, etc., enabling improved wearing comfort and long-term wearability. [14][15][16][17] Besides the wearability of the modules in the IoT system, energy issue is within wide research interest and concern as one of the urgent issues contemporarily. Batteries, as the dominant choices for power supply modules, are now revealed asThe advancement of the Internet of Things/5G infrastructure requires a lowcost ubiquitous sensory network to realize an autonomous system for information collection and processing, aiming at diversified applications ranging from healthcare, smart home, industry 4.0 to environmental monitoring. The triboelectric nanogenerator (TENG) is considered the most promising technology due to its self-powered, cost-effective, and highly customizable advantages. Through the use of wearable electronic devices, advanced TENG technology is developed as a core technology enabling self-powered sensors, power supplies, and data comm...

“…For example, an electronic skin based on a flexible thermoelectric conversion has been reported, which can harvest energy from the body and provide a continuous energy supply [ 161 ]. Recently, another self-powered electronic skin that combined the triboelectric effect with thermoelectric conversion has been proposed, which can simultaneously convert the monitored temperature and pressure into independent signals [ 162 ]. Such self-powered sensors often do not require the integration of additional power modules, which provides a new solution for miniaturized flexible sensors.…”
